GENERAL UTILITY TOOL Fi'led Jan. 29, 1936 mtoMw g Patented May 16, 1939UNITED STATES PATET FFEQE 2 Claims.

My invention relates to utility tools and has for its object to providea tool which has many uses but which tool consists of a main unit andmany supplementary tools and attachments therefor which are to all beused with the main unit.

A further object is to provide a utility tool comprising a motor,driving a set of co-acting opposed gears, which may be either or bothused to drive or actuate different tools, such as shoe shining andpolishing pads, mixing tools, small circular saws, sanding disks,reciprocating saws, knives, and like tools, and any other small type ofreciprocating tool.

These objects I accomplish with the device i1- lustrated in theaccompanying drawing in which similar numerals and letters of referenceindicate like parts throughout the several views and as described in thespecification forming a part of this application and pointed out in theappended claims.

In the drawing in which I have shown my device,

Figure 14 is a section of one of the inner cutters.

Figure 15 is a section of the other cutter.

Figure 16 is an end view of Figure 12.

In the drawing I have shown my motor utility tool as A, having a motor Bformed in a suitable closed cylindrical casing at one end of the tooland extending out from one closed end of the cylindrical casing is acasing 2, surrounding the 65 extended drive shaft of the motor, (notshown).

The end of this shaft casing 2 is formed into a gear housing 3 made byextending two sides 5 and 6 in semi-circular form at the end of thecasing and then providing this with a removable semi-cylindrical casing'1. This casing has one end closed at 8 and the other end is open toallow it to be slid over the sides 5 and 6. In the housing 3, I thenmount a bevel pinion I0 meshing with a bevel gear H, which gear II iscarried on a hollow transverse shaft l2. This shaft is carried mediallythrough the sides 5 and 5 and the sides are formed with suitablehearings to hold the shaft in proper alignment with the pinion and gearin constant meshing position. The ends l3 and M of the shaft l2 extendbeyond the sides 5 and 6 sufficient distance to allow the many difierenttools and attachments to be carried thereon. These two ends l3 and I4are slotted at l5 to allow the proper compression of the shaft forfrictional engagement with the different tools and attachments and tofit the cross plate which is formed in the sockets formed on thesetools.

The saw D in Figure 4 is made with a socket l'l formed on the back sidethereof, said socket to fit onto either stub shaft 13 or 14 with a crossplate l8 formed diametrically across the socket to fit into the slot l5of the stub shafts. This saw may be used for any desired purpose.

In Figure 6 a small size grinding stone E is shown having a socket l9formed on one side with a like plate 20 thereacross. This also may beused on either of the stub shafts l3 or l4.

In Figure 8 I have shown a sanding disk F having sand paper 22 securedto the engaging face and having a socket 23 formed on the back side ofthis disk by which it may be secured to the stub shafts l3 and M.

In Figure 12, the device is made to provide cutt'ers, one stationary,and the other to rotate, with the stationary cutter carried on a crossshaft 68 which cross shaft extends through the core opening of the crossshaft l2 of the tool A. A holding bracket 69 is secured to the casing 2and carries a lug 10 in the end thereof to fit into the socket 1| in theend of the shaft 68, thus holding the shaft and two guard cutters l2 and12a from rotation and the two rotating cutters I3 and 14 are providedwith hubs 15 on the inner side of each to fit onto the stub shafts l3and M of the shaft I2, thus the two inner cutters rotate and the outercutters stand still and the teeth of the inner cutters cut off anymaterial passed through the stationary guard cutters.

Having thus described my invention, I desire to secure by Letters Patentand claim:

1. In a utility tool, the combination of a motor; a drive shaftextending therefrom; a housing around said shaft; an enclosed gearhousing at the end of said shaft housing; a pinion gear mounted on theend of said shaft; a hollow cross shaft mounted across the gear housingat right angles to the motor shaft with each end extended beyond thehousing to receive a tool from either or both sides; a bevel gearmounted on said cross shaft meshing with the pinion gear of the driveshaft to impart motion to the cross shaft; slots through the extendedends of the shaft, a tool having a hollow hub formed on one sidethereof; a plate formed diametrically across said hollow hub from innerside to inner side, said plate to engage within the slots in theextended ends of the cross shaft with the hollow hub encircling theextended ends to firmly engage the tool to the shaft.

2. In a portable small hand operated tool of the class described, thecombination of a small diametered motor mounted with the drive shaftextending through a housing extending from one end of said motor; a gearcasing on the end of said housing; a hollow cross shaft through saidgear casing extending beyond each end of said housing; cross shaft fromthe motor shaft; a stationary shaft through the hollow cross shaftcarrying a toothed cutter guard on each end thereof; means to lock saidstationary shaft by one end to said shaft housing; and rotary toothedcutter blades mounted to rotate with said cross shaft against saidstationary cutter guards.
